100% disk usage in Task Manager when using Photoshop CC (Windows 8.1 - 64 bit)

Hi

I have been using Adobe CC for a month or two now. I own an Asus laptop with Intel i7 (2.4 GHz), 6 GB RAM, 1 TB hard disk space and 64 bit, nearly 6 months old. Following apps are currently installed: Photoshop, Illustrator, InDesign, Audition, Acrobat XI Pro, Premiere Pro and Media Encoder. I recently performed an update through Adobe CC for Photoshop and Illustrator, all others are up-to-date.

I believe, but I may be wrong, that since this update Photoshop is acting weird on my laptop. When I start Photoshop, my task manager immediately indicates a 100% rate of my disk usage. This seems to wield off after it is fully operational, but when I start to edit a file, the disk usage immediately jumps back to 100%, while the CPU remains below 10%, RAM stays at 3.5-3.8 GB (only 60% of total capacity) and even the actual read and write speeds of my HDD are not particularly high (5 - 10MB max). And because of the 100% disk usage, Photoshop freezes in an instant and operating it is nearly impossible.

I already uninstalled Photoshop, went over all services that could trigger this within Windows 8.1 (Google-search for: Windows 8.1 disk usage 100%) , re-installed Photoshop and I still have the same problem.

So, I was wondering if there might be a solution to this problem or if anybody else is having this problem as well?

Thanks in advance!

UPDATE: This error applies only when I try to manipulate, add, edit or remove text. All other functions (not related to text) seem to work properly.
